Teachers at Birmingham’s Small Heath School began a three-day strike today, Tuesday, in an increasingly bitter dispute with school bosses.

A big turnout from supporters from outside the school boosted picket lines while a stream of vehicles tooted their horns in solidarity.

NUT union members are striking in defence of victimised union rep Simon O’Hara. They plan two further three-day strikes in the two weeks after next week’s half term.

One striker told Socialist Worker, “The NUT is going strong and our members are out in full force today. There’s nobody wavering. Simon’s a very hardworking and dedicated teacher. He’s got lots of support.

“I taught a lesson yesterday and the kids were all asking about him. They all say he’s a really good teacher.”

One teacher joined the NUT the day before the strike so they could join the action. Another filled out their NUT membership form on the picket line.

As one teacher told Socialist Worker, “The NUT has grown during this dispute. Strikers are completely united and strong.”

A series of escalating strikes forced bosses to back down at the end of last month over plans to turn the school into an academy. They also retreated on plans to push through 71 job cuts. And two members of the interim executive board that runs the school resigned.

But bosses then suspended another NUT member at the school. One striker said this had “strengthened the resolve of the NUT”.
